Commercial Plumbing Toronto — Licensed, Permitted & Available 24/7
A plumbing failure in a commercial property isn't just an inconvenience — it can shut down your operations, trigger health code violations, and cost thousands in lost business per hour. Emergency Repair Plumbers delivers licensed commercial plumbing services across Toronto and the GTA, from restaurant grease trap installation and office build-outs to 24/7 emergency drain repair for properties of all types and sizes.
Commercial Plumbing Services for Every Property Type
Restaurant & Food Service
Complete commercial kitchen plumbing including drain rough-in, grease interceptor installation, pot fill faucets, commercial dishwasher connections, and health department compliance. We work with Toronto Public Health food service plumbing requirements and the Toronto Sewer Use Bylaw grease interceptor standards. Available for new restaurant fit-outs, equipment changeouts, and emergency drain service.
Office Buildings
Plumbing services for office towers, professional suites, and mixed-use commercial buildings across Toronto's downtown core and midtown. From tenant improvement rough-in and washroom upgrades to backflow preventer testing, booster pump systems, and after-hours emergency response. We coordinate with building management and property standards teams to minimize disruption to tenants.
Retail Spaces
Plumbing for retail fit-outs and tenant improvements in Toronto's retail districts, shopping centres, and standalone commercial properties. We handle washroom installations, break room plumbing, sump and floor drain systems for receiving areas, and water supply for specialty retail applications. We work within tight construction schedules to meet landlord and tenant move-in deadlines.
Industrial Facilities
Heavy-duty plumbing solutions for manufacturing plants, warehouses, and industrial facilities in the GTA. Industrial plumbing involves larger pipe diameters, floor drain systems designed for process water and equipment washdown, pressure booster systems, and compliance with the Ontario Building Code industrial plumbing requirements and MOE discharge standards. All work performed by licensed 306A tradespeople.
Multi-Unit Residential
Plumbing services for condominium buildings, apartment complexes, and multi-unit residential properties throughout the GTA. We manage common-area plumbing systems, in-suite repair and renovation, stack cleaning, backflow preventer testing, boiler and domestic hot water system servicing, and coordination with condominium management corporations. Available for both planned maintenance and emergency response.
Healthcare & Medical
Specialized plumbing for medical offices, dental practices, physiotherapy clinics, and small healthcare facilities. Healthcare plumbing involves specific requirements for water quality, backflow prevention, sanitary fixture clearances, and medical gas rough-in coordination. We are familiar with Ontario's infection control requirements for healthcare facility plumbing and with the Toronto Building Division's requirements for Change of Use permits in medical occupancies.
Restaurant & Food Service Plumbing in Toronto
Restaurant plumbing in Toronto operates under a distinct regulatory framework that combines the Ontario Building Code commercial plumbing requirements with Toronto Public Health food premises inspection standards and the Toronto Sewer Use Bylaw grease discharge requirements. A plumbing failure in a commercial kitchen can trigger an immediate closure order from a Toronto Public Health inspector — making both preventive maintenance and fast emergency response essential for food service operators. Grease-laden wastewater that bypasses interceptors can also cause sewer line damage further down the system, compounding your liability.
Restaurant Plumbing Services We Provide
- • Commercial kitchen drain rough-in: Floor drain layout, slope, and connection to sanitary system for new restaurant fit-outs and kitchen reconfigurations. All rough-in is permitted and inspected by the Toronto Building Division.
- • Grease interceptor installation and sizing: Proper sizing of commercial grease traps per the Toronto Sewer Use Bylaw requirements, based on your kitchen's flow rate and operating hours. We install in-ground and under-sink interceptor units.
- • Three-compartment sink plumbing: Supply and drain connections for commercial warewashing per Ontario Food Premises Regulation requirements, including indirect waste connections where required.
- • Commercial dishwasher connections: Hot water supply, drain, and indirect waste connections for commercial glasswashers and conveyor dishwashers. Booster heater installation where required to meet minimum rinse temperatures.
- • Pot fill faucet installation: Above-range pot fill arm installation with properly sloped drain, connected to the cold water supply with appropriate backflow protection.
- • Handwashing station compliance: Toronto Public Health requires dedicated handwashing sinks in commercial kitchens. We install and connect compliant handwashing stations to meet inspection requirements.
Toronto Restaurant Plumbing Regulations
Ontario Food Premises Regulation (O. Reg. 493/17)
Provincial regulation governing food premises operations, including requirements for hot and cold running water, handwashing facilities, three-compartment sinks, and washroom access for staff. All plumbing in food premises must comply with the Ontario Building Code and this regulation.
Toronto Sewer Use Bylaw — Grease Interceptors
Commercial kitchens that discharge grease-bearing wastewater to the municipal sewer system are required under the Toronto Sewer Use Bylaw to maintain functioning grease interceptors. Non-compliant grease discharge can result in surcharges, enforcement action, and contributing to sewer blockages in the city's collection system.
Toronto Building Division — Commercial Permits
All commercial plumbing installations — including new restaurants, kitchen fit-outs, and significant equipment changes — require a plumbing permit from the Toronto Building Division. Permit drawings, inspections, and sign-off are part of the process. We handle permit applications and coordinate inspections on your behalf.
Commercial Grease Trap Installation & Maintenance in Toronto
Grease interceptors — commonly called grease traps — are mandatory for commercial kitchens in Toronto. They prevent fats, oils, and grease (FOG) from entering the municipal sewer system, where they solidify and contribute to sewer blockages that affect entire city blocks. A properly sized, maintained grease interceptor protects your restaurant from enforcement action, sewer backup, and costly emergency drain service calls.
Step 1: Sizing & Selection
We calculate the required interceptor size based on your kitchen's drainage flow rate, number of fixtures, and operating hours. Undersized grease traps are a common compliance failure. We specify the correct unit size per the Toronto Sewer Use Bylaw requirements and available space constraints.
Step 2: Permitted Installation
Grease interceptor installation requires a plumbing permit from the Toronto Building Division. We prepare permit documents, coordinate the installation of the interceptor with proper inlet, outlet, and access for cleaning, and arrange for the required Building Division inspection and sign-off.
Step 3: Maintenance Contract
Toronto Public Health food service inspectors check grease interceptor condition at every restaurant inspection. A regularly maintained, properly functioning interceptor is required. We offer scheduled maintenance contracts — typically quarterly or semi-annual cleaning — and provide documentation of service for your inspection records.
Critical: Blocked Grease Traps Are the #1 Cause of Commercial Kitchen Drain Backups
When a grease interceptor exceeds 25% capacity with accumulated FOG, it becomes ineffective and allows grease to pass through to the sewer system. When the interceptor fills completely, drain backups in the kitchen are inevitable — and can occur during peak service, forcing emergency closure. Regular scheduled cleaning is a mandatory operational requirement for every commercial kitchen in Toronto.
Office Building & Commercial Tenant Improvement Plumbing
Commercial tenant improvement (TI) projects — fit-outs for new office tenants, retail spaces, medical offices, and other commercial uses — frequently require new or modified plumbing to meet the specific requirements of the incoming tenant and the applicable Ontario Building Code occupancy requirements. Commercial TI plumbing requires coordination across multiple stakeholders and a clear understanding of permit and inspection requirements in the City of Toronto.
What Commercial TI Plumbing Involves
Ontario Building Code Commercial Plumbing Requirements
The Ontario Building Code (OBC) sets minimum plumbing standards for all commercial occupancies. Key commercial requirements include:
- ✓ Minimum fixture counts based on occupancy type and expected occupant load
- ✓ Accessible washroom requirements under OBC accessibility provisions
- ✓ Backflow prevention for all commercial water supply connections
- ✓ Hot water supply requirements for specific commercial uses (food service, healthcare)
- ✓ Venting requirements for all commercial drainage systems
- ✓ Specific requirements for Change of Use permits when an existing space changes occupancy classification
TSSA (Technical Standards and Safety Authority) regulates gas-line work in Ontario commercial buildings. All commercial gas-line installation and modification requires a licensed gas technician and TSSA permit — separate from the building permit.
Commercial Plumbing Permits & Regulations in Toronto
Commercial plumbing in Toronto operates under a multi-layered regulatory framework. Understanding which regulations apply to your project — and which permits are required — is essential to avoiding stop-work orders, failed inspections, and compliance enforcement by the City of Toronto or provincial bodies.
Toronto Building Division — Commercial Permits
The Toronto Building Division administers building permits for all commercial plumbing installations under the City's authority as a municipality under the Building Code Act. A commercial plumbing permit is required for:
- • Any new commercial plumbing installation
- • Significant alteration or relocation of existing commercial plumbing
- • Change of use that affects plumbing requirements
- • Grease interceptor installation
- • Backflow preventer installation on commercial supply
TSSA — Gas-Line Work in Commercial Buildings
The Technical Standards and Safety Authority (TSSA) regulates natural gas installations in Ontario. Commercial gas-line work — including connections for commercial kitchen equipment, HVAC units, and heating systems — requires a TSSA-licensed gas technician (G1 or G2 licence) and a separate TSSA permit, independent of the building permit. All gas work must pass TSSA inspection before connection to the gas supply.
Our licensed team includes qualified gas technicians for commercial gas-line coordination where required on kitchen and HVAC projects.
Toronto Property Standards Bylaw — Commercial Properties
Toronto's Property Standards Bylaw imposes ongoing maintenance requirements on commercial property owners and tenants. Plumbing systems must be maintained in good working order; failure to address reported plumbing deficiencies — leaking pipes, non-functioning fixtures, blocked drains — can result in Property Standards orders and fines. We assist commercial property managers with Property Standards compliance work.
Ontario Building Code — Backflow Prevention
The OBC requires backflow prevention on commercial water supply connections where there is risk of contaminated water being siphoned back into the potable supply. This is especially important in healthcare facilities, laboratories, food processing operations, and properties with irrigation systems or fire suppression connections. Annual backflow preventer testing is required on most commercial applications.
We Handle the Permit Process End-to-End
Navigating Toronto's commercial permit process can be time-consuming for contractors and business owners who are unfamiliar with it. We prepare permit drawings, submit applications to the Toronto Building Division, respond to any reviewer comments, schedule required inspections, and obtain permit close-out on your behalf. We also coordinate with TSSA for any gas-related components. Contact us to discuss your project's permit requirements.

A plumbing emergency at a commercial property can mean immediate revenue loss, forced closure, health code violation, and damage to tenant relationships. Unlike residential emergencies, commercial plumbing failures often occur during business hours and must be resolved quickly to minimize impact on operations, staff, and customers.
Commercial Emergencies We Respond To
Drain Backup in Commercial Kitchen
A backed-up floor drain in a restaurant kitchen triggers a mandatory closure under Toronto Public Health food premises regulations. We dispatch immediately for commercial kitchen drain emergencies across the GTA.
Burst Pipe or Water Main Break
A burst pipe in a commercial building can flood office suites, retail spaces, and common areas within minutes. We isolate the leak, stop the damage, and restore service as quickly as possible to minimize business interruption.

A failed backflow preventer that allows contaminated water into the building supply is a health emergency. We respond 24/7, isolate the water supply, replace the failed device, and coordinate with Toronto Public Health as required.
Washroom Failure in Office or Retail
A non-functional washroom in a commercial space may violate the Ontario Employment Standards Act and Property Standards Bylaw. We restore service quickly for office and retail properties with tenant and building management coordination.

Frequently Asked Questions — Commercial Plumbing Toronto
Do you offer emergency commercial plumbing in Toronto?
Yes. We provide 24/7 emergency commercial plumbing response throughout Toronto and the GTA. Our commercial emergency line — (289) 514-1836 — is answered live at all hours by a dispatcher who can deploy a licensed commercial plumber to your property. There is no answering service and no callback queue for declared commercial emergencies.
We understand that commercial plumbing failures — particularly in restaurants, healthcare facilities, and high-traffic retail locations — are operational emergencies that cannot wait for the next business day. Our service vehicles carry commercial drain equipment, pressure testing gear, pipe repair materials, and replacement fixtures for the most common commercial emergency scenarios. We provide a written service report after every commercial call, suitable for insurance documentation, property management records, and Toronto Public Health inspector inquiries.
What types of commercial properties do you serve?
We serve all commercial property types throughout Toronto and the GTA, including restaurants and food service operations, office buildings and professional suites, retail and mixed-use commercial properties, industrial and manufacturing facilities, multi-unit residential buildings, and healthcare and medical offices.
Each property type has specific plumbing code requirements, permit processes, and operational considerations. Restaurants must comply with Toronto Public Health food premises plumbing standards and the Toronto Sewer Use Bylaw for grease discharge. Healthcare facilities have specific infection control plumbing requirements. Industrial properties may need to meet the Ontario Ministry of the Environment's discharge quality standards. Multi-unit residential buildings require coordination with property management and condo corporations. We are familiar with the applicable requirements for each property type and bring this expertise to every commercial job.
Are your plumbers licensed for commercial work in Ontario?
Yes. All of our plumbers hold valid Ontario Certificate of Qualification (306A) journeyman plumber licences issued by the Ontario College of Trades. In Ontario, plumbing work in commercial buildings — including restaurants, offices, retail, and multi-unit residential — must be performed by or under the direct supervision of a 306A licensed tradesperson.
We carry full commercial general liability insurance and WSIB (Workplace Safety and Insurance Board) coverage on all commercial jobs — documentation available on request for any project. We also maintain the necessary registrations with the Toronto Building Division to obtain commercial plumbing permits, and we coordinate with TSSA for any gas-line work that accompanies commercial plumbing projects. We do not subcontract core plumbing work to unlicensed trades on commercial projects.
Do you install commercial grease traps in Toronto restaurants?
Yes. We install, replace, and service commercial grease interceptors for Toronto restaurants and food service establishments. Grease interceptor installation and maintenance is a specific area of expertise for our commercial team, given that it touches both the building permit process and Toronto Public Health food premises compliance simultaneously.
We size interceptors per the Toronto Sewer Use Bylaw requirements and the applicable flow calculations for your kitchen's fixture count and operating hours — undersized interceptors are a frequent compliance failure that triggers enforcement action. We pull the required Toronto Building Division plumbing permit, install the unit with proper connections and access for cleaning, and arrange for the required inspection and permit close-out. We also offer scheduled maintenance contracts to ensure ongoing compliance: Toronto Public Health inspectors check grease interceptor condition at every food premises inspection, and a clogged or non-functional interceptor can result in immediate closure of your restaurant.
Can you handle plumbing for a commercial tenant improvement (TI) project?
Yes. We are experienced in commercial tenant improvement plumbing throughout Toronto. TI projects require coordination across multiple parties — the general contractor, the building owner, the tenant, and the Toronto Building Division — and a clear understanding of how commercial permit applications, rough-in inspections, and permit close-out work in practice.
We can engage at any stage of a TI project: from pre-design consultation on plumbing layout options and permit requirements, through permit application and rough-in, to finish plumbing, inspection scheduling, and final documentation. For general contractors who work in Toronto commercial spaces regularly, we offer trade pricing and can be carried as a named subcontractor on your TI packages. Projects typically range from small office washroom upgrades to complete multi-floor fit-outs for restaurant, retail, or office tenants. Contact us to discuss your project scope and timeline.
